HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

2-Bromo-3-methylbenzo[b]thiophene serves as a pivotal building block in the synthesis of functionalized heterocycles. This brominated thiophene derivative features a sterically accessible halogen site and an electron-rich methyl group, enabling efficient cross-coupling reactions. Its bench-stable nature supports reliable use in transition metal-catalyzed transformations.

Application

2-Bromo-3-methylbenzo[b]thiophene serves as a versatile building block for the synthesis of functionalized heterocycles and pharmaceutical intermediates. Its bromine atom enables palladium-catalyzed cross-coupling reactions, while the methyl group provides a site for selective oxidation or further functionalization. The molecule exhibits good bench stability and is compatible with standard synthetic workflows, facilitating efficient access to complex scaffolds in medicinal chemistry and materials science.
